Question

Explain the architecture of Bluetooth technology with suitable diagram.

Answer 1

Bluetooth is short range wireless technology. Range of Bluetooth is 10 meters.

Bluetooth Architecture defines 2 types of networks.

1)Piconet

2)Scatternet

Piconet: - It is a Bluetooth network that consists of one primary (master) node and seven active secondary (slave) nodes. It can have 8 active nodes within the distance of 10 meter. Communication between primary and secondary can be one-to-one or one-to-many. All communication is between master and slave.

There can be only one primary or master station in each piconet.

Scatternet: - Scatternet is formed by combining various piconets. Slave in one piconet acts as a master or primary in other piconet. A node can receive messages from master in first piconet and deliver the messages to its slave in other piconet where it is acting as master. This node is called bridge slave. This node cannot be the master of two piconets.
